160 meters is MF, not HF. > Hopefully, others will have a lot more understanding than I have on what > it is they are permitting on the "data" portions of the bands which to > me means anything that is not the phone section.

Else the digital bands could be filled with wide SSTV, leaving no room for RTTY, PSK31 and the like. Just look at the havoc that 2KC-wide Pactor 3 signals are wreaking already. Despite the paranoid rants posted earlier, the intent of this rule change, as I understand it, is merely to allow US hams to use the analog image feature of MFSK16 (which is no wider than the digital text mode, just 316 Hz); to solidify the legal status of Feldhell, considered by some interpretations to be an image mode, either analog or digital depending on how you look at it; and permit future experimentation with similar modes. -Joe, KD8ATU Need a Digital mode QSO?
